We also computed the False Inclusion Probability (FIP) and True Inclusion Probability (TIP) from the joint posterior distribution of orbital parameters and \(N_{p}\) . [1]} introduces the FIP as the probability that there is no planet with period \(P\)  in a given frequency interval \(I\) . On the other hand, the TIP is defined as the counterpart of the FIP, that is, the probability that there is a minimum of one planet with \(P\)  \(\epsilon \)  \(I\) .
The TIP is calculated by averaging the planet detection over the possible number of planets, \(\frac{N_{p}(i)}{\Sigma \, \,N_{p}}\) . [1]} presents this detection criterion as an efficient way to evaluate the reliability of significance levels, by effectively accounting for aliases and favouring to discard the presence of planets under a certain confidence level.
